About intelligent expression grading
When you create an expression question and correct answer, intelligent expression
grading accepts multiple representations of that answer expression as correct.
A student’s answer is always graded correct if it:
l matches the question's correct answer exactly
l has a different representation, but is mathematically equivalent and uses the same
terms and operators in the same order as the question's correct answer
You can use intelligent grading options to decide which other mathematically equivalent
answers you’d like to accept as correct. The following graphic shows the three levels of
equivalency that you can define for your questions.
The following table shows examples of how SMARTResponse's intelligent expression
grading compares expression answers to the question's correct expression answer.
